Work with ROCK Pi E Ubuntu
Introduction to ROCK Pi E Ubuntu
ROCK Pi E UBuntu is an easy to use system. While working with ROCK Pi E Ubuntu, you will find it do well on playing music, playing video, Internet, Bluetooth and so on.
ROCK Pi E Debian uses systemd to manage system.
Here Need one USB to TTL serial cable. Or use SSH.
UBuntu Default User Account
Non-root User:
User Name : rock Password : rock
Install and update necessary packages
Add Radxa APT, see Radxa APT.
Install packages;
$ sudo apt-get update $ sudo apt-get install -y rockchip-overlay $ sudo apt-get install -y linux-4.4-rockpie-latest
Network Connection
There are two methods for network connection. One is Ethernet and the other is WIFI.
Ethernet Connection
ROCK Pi E provides dual ethernets. You can use two network cables at the same time to connect your ROCK Pi E to the network. The ROCK Pi E will automatically configure the network for your surfing on the Internet.
To test the Ethernet, we need to follow the steps:
- Switch to super user mode by command
$ sudo su
- Check whether the Ethernet is normal by command, ifconfig, which would show us two network cards, eth0 and eth1, and the Ethernet IP address. Also, use tool, ping, to connect to a normal domain.
$ ifconfig $ ping -I eth0 www.baidu.com $ ping -I eth1 www.baidu.com
WiFi Connection
When there is not a network cable for your ROCK Pi E the WIFI connection is another good choice. ROCK Pi E supports 2.4G/5G WiFi wireless network.
To test the WiFi performance, we need to follow the steps:
- Switch to super user mode
$ sudo su
- Open the WiFi
$ nmcli r wifi on
- Scan WiFi
$ nmcli dev wifi
- Connect to WiFi network
$ nmcli dev wifi connect "wifi_name" password "wifi_password"
- Test WiFi perpormance by tool iperf.
Bluetooth
Update necessary packages
$ sudo apt-get update $ sudp apt-get install -y rockchip-overlay $ sudo apt-get install -y linux-4.4-rockpie-latest # kernel version(>=4.4.194-7-rockchip) $ sudo apt-get install -y realtek-bt-firmware bluez
Check Bluetooth service
$ systemctl status bluetooth
Run Bluetooth service if the Bluetooth service is inactive.
$ systemctl start bluetooth
Start realtek-btfw-load service
$ systemctl start realtek-btfw-load
Check Bluetooth device
$ hciconfig root@rockpie:~# hciconfig hci0: Type: Primary Bus: USB BD Address: 7C:A7:B0:22:82:C5 ACL MTU: 1021:8 SCO MTU: 255:12 UP RUNNING PSCAN RX bytes:5120 acl:0 sco:0 events:100 errors:0 TX bytes:2904 acl:0 sco:0 commands:74 errors:0
Example: Connect to Bluetooth Speaker.
Change to root mode.
$ sudo su
Install pulseaudio packages
# apt-get install -y pulseaudio-module-bluetooth pulseaudio
Run pulseaudio
# pulseaudio --start
Connect using bluetoothctl
# bluetoothctl [bluetooth]# default-agent [bluetooth]# power on [bluetooth]# scan on [bluetooth]# trust 77:EC:79:4F:6B:AC [bluetooth]# pair 77:EC:79:4F:6B:AC [bluetooth]# connect 77:EC:79:4F:6B:AC
Play songs and enjoy it.
Common Hardware Interfaces, I2C, SPI, UART, etc
The ROCK Pi E system images use /boot/uEnv.txt to configure hardware interfaces.
Remember there is only one line includeing item "overlays=" in file /boot/uEnv.txt.
For more details about device tree overlays, see Device Tree Overlays.
I2C
To enable I2C-1 (/dev/i2c-1), add item "rk3328-i2c1" to the "overlays=" line.
overlays=rk3328-i2c1
SPI
To enable SPI0, add item "rk3328-spi-spidev" to the "overlays=" line.
overlays=rk3328-spi-spidev param_spidev_spi_bus=0 param_spidev_spi_cs=0 param_spidev_max_freq=10000000
UART
The debugger console baud rate options: 1500000n8 and 115200n8.
To set ttyS1 as debugger console, add item "rk3328-uart1" to the "overlays=" line. Also need to set console value.
console=ttyS1,1500000n8 overlays=rk3328-uart1
To set ttyS2 as debugger console, add item "rk3328-uart2" to the "overlays=" line. Also need to set console value.
console=ttyS2,1500000n8 overlays=rk3328-uart2
To set ttyS1 as common serial communication, add item "rk3328-uart1" to the "overlays=" line. The device /dev/ttyS1 is available.
overlays=rk3328-uart1
To set ttyS2 as common serial communication, add item "rk3328-uart2" to the "overlays=" line. The device /dev/ttyS2 is available.
overlays=rk3328-uart2
